	The Elanin Singer Stone gives a different tune to each person that holds it, but doesn't respond to Data.
	The Computer offers Picard a variety of mounts on the holodeck including an Andorian Zabathu and a Klingon Sark. He declines the offers and chooses an Earth mount of Arabian breed.
	Pulaski has the knowledge to erase specific memories. She describes: "Assuming the brain structure is similar to ours the memories will be stored chemically on the neurons of the cerebral cortex. They are also time dependent. I'll have to scan for age of the chemical links, and try to find the relevant neurons. To be sure I may have to go back weeks before the initial contact with Data." This process is also referred to in season three's "Who Watches the Watchers"
	UV Absorption readings of a specific nature are usual indicative of Tracker deposits, which in turn normally indicate Dilithium is present. To confirm the presence of Dilithium, it is normally appropriate to run an Ico-Spectrogram, sometimes abbreviated to an "icogram".
	Dilithium crystals present in a planet's crust can cause major geological instability, as experienced the Dremans on Drema IV.
	Troi had a kitten when she was young, but her mother disliked it intensely. Betazeds are not very good at reading animal's emotions.
	Picard is a horse-lover (see also "Starship Mine" and Star Trek Generations).
	Riker has been given the role of overseeing Wesley's education.
